HORSESHOE-BLANK BAR.

SPECIFICATION forming part of Letters Patent No. 449,054, dated March24, 1891.

Application filed September 29, 1890. Serial No. 366,534. (No model.)

T 0 all whom it may concern.-

Be it known that 1, CHARLES HENRY PER- KINS, of the city and county ofProvidence, in the State of Rhode Island, have invented certain new anduseful Improvements in Horseshoe-Blank Bars; and I do hereby declarethat the following specification, taken in connection with the drawingsfurnished and forming a part of the same, is a clear, true, and completedescription of my invention.

My said blank-bars are specially designed to be cut into blanks for usein making plain ordinary toe-weighted horseshoes, as distinguished fromthe higher grades of such shoes, which are provided with an innerbeveled edge, for the making of which blanks and blank-bars have beendevised by me and m adc the subject of a separate application-forLetters Patent. (See Serial No. 366,218.)

My plain blank-bar, which is the subject of this application, containstwo lines or series of blanks for plain toe-weighted shoes, audit is astraight-edged bar of metal of uniform thickness, provided on one sidewith appropriate nail-creases for each line of blanks, said creasesbeing located near the two edges of the bar, and those of one series areoffset with relation to those of the other series. In other words, theportions of the nail-scores of each blank which are to be occupied bynails are in part diagonally opposite the corresponding portions ofnail-scores of two laterallyadjacent blanks, because the blanks as theylie in the bar have the ends of two heel portions laterally opposite thecenter of the toe portions of the laterally-adjacent blank. Thisdiagonal arrangement of the nail-creases is not, however, restricted toplain shoe-blank bars.

Referring to the drawings, Figure 1 in top view and several sectionsillustrates my novel blank-bar. Fig. 2 illustrates one of the blanksdetached. Fig. 3 illustrates a plain toe- Weighted shoe as produced fromsaid blank.

The blank-bar A is uniform in width and thickness, and it may be of anydesired length. It essentially differs from a plain bar of metal in thefact that it has nailscores which are of such character and so locatedor offset with reference to each other that when out on a zigzag lineinto blanks a the toe portion a, of each blank will be opposite the heelportion a of two laterallyadjacent blanks, and the portions of thenailcreases which are to be occupied by nail-'55 heads will be locatedin each blank nearer to the toe than the heels. It will be obvious thatif the bar be continuously creased or scored the blanks will not beimpaired, such a crease being common to some forms of 0 shoes. Thepresence of such a crease will mot adversely affect the character of mybar,

as it willin no mannerinterfere with the cutting of the blanks from thebar. I prefer, however, the separate creases shown, properlyproportioned in length, and provided with depressions or head-prints,into which the heads of nails maybe snugly housed and enabling thenail-hole-punching operation to be easily performed. The portion of thenail- 7o crease which is to be occupied by nail-heads is of course theonly essential portion of each crease, and hence those portions must beoffset with relation to those in the laterally-adjacent blank or blanks.

No gage-marks are necessary for indicating the zigzag line on which theblanks are to be separated, although said line is indicated in dottedlines in Fig. 1, the separation being performed preferably by ashearing- 8o punch having the precise contour desired and of the exactlength of a blank, those on one side being first detached, leaving theremaining blanks still connected at their heel portions to be separatedby means of proper shears.

As length gage-marks are desirable, the bar is notched at both of itsedges, as at b, and these notches on one side alternate in position withthe notches on the other side, thus clearly defining the zigzagparting-line, which is straight from the inner end of any one notch tothe inner end of either notch at the other edge of the bar.

Blank-bars embodying valuable features of 5 my invention may becontinuously scored along each edge of the bar it said bar be no widerthan the combined width of the wide toe portion and that of the narrowheel portion, and the score may be provided at regu- 10o lar intervalswith head-prints for nails, because some shoes are thus continuouslyscored .patent.

from heel to heel, and those heel-prints not afterward punched for usewould be mere surplusage and not specially detrimental to the shoe, itbeing obvious that such a bar, when divided on the zigzag linedescribed, would afford plain toe-weighted blanks, and each of these inthe bar would have laterally opposite its toe portion the heel portionsof two adjacent blanks.

This blankbar is produced in accordance with a novel method or processdisclosed in my application for Letters Patent, filed August 14, 1890,Serial No. 361,962, and by means of mechanism which also has been madethe subject of a separate application for (See Serial No. 365,939.)

It is to be understood that after the single blanks have been cut fromthe double bar, as hereinheforc described, a sin gle-line blank-barremains, which is in a form well suited either for the use of suchhorseshoers as may prefer to do their own bending or fol-immediateconversion into shoes, and such blank-bars are to be made the subject ofa separate application for Letters Patent. (See Serial No. 366,723.)

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- 1. A straight-edged blank-bar containing toe-weightedhorseshoe-blanks, said bar having on one side near both edgesappropriate naihscores, the nail-prints in the scores near one edgebeing diagonally opposite the laterally-adjacent scores.

2. A blank-bar affording blanks for making plain toe-weightedhorseshocs, said bar be ing of uniform thickness and width,appropriately scored near each edge on one side, and having thoseportions of the scores which are to be occupied by nail-heads near oneedge of said bar ottset with relation to correspond ing portions of thescores near the opposite edge, said bar being adapted to be cut inzigzag lines between the two lines of scores and locating opposite thetoe portion of each blank two heel portions of laterall y-ad j acentblanks.

3. A straight-edged blank-bar provided with nail-scores near andparallel with both edges, and gageqnarks which at one edge are diagonally opposite the adjacent gage-marks at the opposite edge, said marksdefining the ends of blanks and indicating a parting-line from eachgage-mark to the nearest gage-mark at the opposite edge of the bar.

4. A straight-edged blank-bar of uniform and proper thickness fortoe-weighted horseshoes and having a width equal to the combined widthof the broad toe of a shoe and of its narrow heel scored on one sidenear and parallel with both edges and affording blanks in two lines, thetoe portion of each being opposite the heel portions of two1aterally-adjacent blanks.
